The best idea is ioroot. It roots most LG phones with kitkat firmware. Check it on xda.
But the problem is that we need to get to recovery. But button combinations and adb command do not boot to recovery, only normal boot.
No root till we find the way to boot it to recovery.

Found a way to get it into recovery use command "adb shell" first then reboot recovery
